Wrench, MEGA bent ring wrench 21 x 23 mm model 36551

Bent ring wrench MEGA model 36551 with 21 x 23 mm sizes is a compact hand tool designed for turning nuts and bolts in confined or angled spaces. Each end features a closed ring profile with an offset (bent) design that improves access to fasteners recessed or obstructed by nearby components. The wrench is intended for metric 21 mm and 23 mm hex fasteners and suits workshop, automotive repair and general maintenance where a compact angled ring wrench is required.

Advantages

The bent ring design provides improved access to fasteners located in tight or awkward positions, reducing the need to reposition surrounding parts. Closed ring ends offer full contact with the fastener head, minimizing slippage and protecting fastener edges. The dual-size configuration (21 mm and 23 mm) on a single tool reduces the number of separate wrenches needed and saves space in a toolbox. Its compact length and offset heads make it easier to work at angles compared with straight ring wrenches.

Suitable for

• Automotive repair: brake, suspension and engine component work where access is limited
• Workshop maintenance and assembly tasks involving metric 21 mm and 23 mm fasteners
• General maintenance: plumbing fixtures, machinery, and equipment with recessed bolts or nuts
• Situations requiring compact, angled access or where clearance around the fastener is restricted

Key specifications

• Working sizes: 21 mm and 23 mm
• Type: bent (offset) closed ring wrench at both ends
• Contact profile: full ring (12-point or 6-point depending on manufacturer profile) for secure grip on hex fasteners
• Application: manual hand tool for turning metric hex nuts and bolts
• Form factor: compact, angled head design for improved clearance

How to use

Select the correct end (21 mm or 23 mm) to match the fastener head. Position the closed ring fully over the nut or bolt to ensure full contact, then apply steady torque in the required direction. Use short, controlled leverages in confined spaces to avoid damaging the tool or fastener. If additional torque is required, ensure the tool is properly seated on the fastener before applying increased force. Avoid using the wrench as a hammer or prying tool to preserve its shape and contact surfaces.

Usage recommendations

Inspect the ring contact surfaces before use and keep the wrench clean and free of oil for optimal grip. Use the wrench within its intended hand-tool torque range and avoid extension with pipes or cheater bars. Store in a toolbox or rack to prevent rounding of the ring edges and to keep the offset heads true for reliable access in tight spaces.
